Whether you need micro-discs just a few millimeters in diameter or thick, heavy-duty blocks, we manufacture all magnets using high-performance sintered NdFeB (Neodymium Iron Boron) according to your precise engineering drawings. NdFeB is the strongest commercially available permanent magnet material, offering the highest magnetic energy product (BH max) and exceptional pull force. Each N52 NdFeB magnet is produced with strict control over raw material purity—neodymium (Nd), iron (Fe), and boron (B)—to ensure maximum performance and long-term reliability.
Our neodymium disc magnets, strong magnetic discs, and round permanent magnets deliver superior magnetic strength while maintaining precise dimensional tolerances, allowing for custom size magnets tailored to your exact specifications. These magnets are ideal for applications ranging from precision electronics, sensors, and office organizer accessories to industrial machinery and automation equipment.
With advanced sintering and quality control, including coercivity (Hc) and remanence (Br) optimization, our magnets provide excellent thermal stability, minimal magnetic decay under mechanical stress, and design flexibility for even the most complex magnetic circuits.
Customization Capabilities
We offer custom round neodymium disc magnets tailored to your specific size, grade, coating, and strength requirements. Each neodymium disc magnet is manufactured with precision using high-quality NdFeB magnet material, ensuring consistent high strength magnet performance for industrial, electronic, or DIY applications.
Our small disc magnets can be customized in diameter, thickness, and magnetic force to perfectly match your project needs. The round magnet design allows easy integration into assemblies, machinery, or craft applications. With corrosion-resistant coatings and strict quality control, these custom neodymium disc magnets deliver reliable durability and long-term performance.
Whether for prototyping, mass production, or specialized applications, our custom high strength neodymium magnets provide the flexibility and quality you need for efficient and precise magnetic solutions.
